Combi Tapping Die M5 x 57 mm 1/4" - MILWAUKEE

MILWAUKEE Combi Tapping Die M5 x 57 mm (1/4") is a hand-tool attachment designed for cutting and restoring metric M5 threads. The tool features a 57 mm die body with a 1/4" drive interface, allowing it to be used with compatible holders and manual drive tools. It is intended for threading, thread repair and maintenance on metal components commonly encountered in workshops, construction sites and repair tasks.

Advantages

The combi tapping die combines thread cutting and repair capability in a single unit, reducing the need to switch between separate tools. Its 57 mm die body provides stable engagement with the workpiece, while the 1/4" drive fit ensures compatibility with standard drive holders and manual adapters. The design is suitable for repeated use in maintenance environments and for restoring worn or damaged M5 threads to specified dimensions.

Suitable for

• Cutting new M5 threads in metal components
• Repairing or restoring damaged M5 threads
• Maintenance work in workshops and service centers
• On-site repairs in construction and mechanical repair tasks

Key specifications

• Thread size: M5 (metric)
• Die body length: 57 mm
• Drive connection: 1/4" drive fit
• Intended use: cutting and repairing internal or external threads depending on application
• Material compatibility: suitable for use on common metal workpieces (steel, aluminum, alloys) when used with appropriate technique and lubrication

How to use

Secure the workpiece and ensure the hole or stud is properly prepared for M5 threading. Mount the combi tapping die in a compatible 1/4" drive holder or manual adapter. Apply appropriate cutting lubricant to the work area to reduce friction and chip formation. Align the die square to the axis of the hole or stud and start cutting with steady, controlled rotations; reverse periodically to clear chips if cutting a through-thread or to break chips in blind holes. After threading or repair, clean chips and lubricant from the thread and inspect fit with a gauge or mating fastener.

Usage recommendations

Use appropriate personal protective equipment and cutting fluid. For hardened or abrasive materials, select proper lubrication and take light cuts to avoid premature wear. When restoring damaged threads, inspect the surrounding material for deformation before using the die to ensure a reliable thread repair.
